Answer:
Let's complete the square first.
y = x² + 6x + 3
= (x² + 6x + 9) - 6
= (x + 3)² - 6
Therefore, the vertex is (-3, -6) and since the coefficient of (x + 3)² is positive, the vertex is a minimum.
The answer is going to be .65 because
1)You subtract 2.95 from 3.6
=3.6-2.95=.65
2)You add 2.95+.65
=3.6
